Easy packing deep container

ABSTRACT

An easy packing deep container is made from a cut and scored blank of paperboard or the like and comprises opposed pairs of main panels connected along lines of fold to define a tube. One of the main panels is split and is composed of half panel sections part of which are overlapped and joined by gluing or the like. The unjoined parts have scores commencing at the point where they are joined and terminating at corners thereof to define triangular shaped subpanels which may be folded out of the way for loading of the container. Closure flaps extend from one end of the main panels and are foldable to position to define an end closure for the tube. Other closure flaps extend from the opposite edges of the split main panel and are foldably connected thereto to define a pair of minor closure flaps. The triangular shaped subpanels are foldable back into a common plane to complete the loading of the tube, and the other closure flaps are thereafter foldable into overlapping and secured relationship with the other closure flaps after completing of the loading of the tube.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates generally to containers adapted to ship bulkymaterial having low density, and which can be shipped in large sizecontainers except for the fact that the loading thereof is not easilyaccomplished. According to the invention, deep loading is accomplishedby providing a front main panel comprised of two half panel sectionswhich are joined along the lower parts thereof, and of other halfsections having diagonally extending score lines to define triangularshaped subpanels foldable out of the plane of the front main panelduring the loading, such subpanels being thereafter foldable intoposition together with minor closure flaps extending therefrom. Theminor closure flaps cooperate with other closure flaps to complete theclosing of the container.

2. The Prior Art

The prior art is best exemplified in the following U.S. Pat. Nos.developed in a search: Belsinger, 2,512,539, June 20, 1950, 229/6;Belsinger, 2,635,802, Apr. 21, 1953, 229/16; Belsinger, 2,648,480, Aug.11, 1953, 229/7.

The present construction represents an advantage over the prior artsince it materially improves the stacking strength of the container.While the prior art discloses containers having vertical and horizontalslits in a main panel thereof, the present construction has only asingle vertical opening, thus reducing the weakening effect on thecontainer caused by a plurality of slits.

SUMMARY OF THE INVENTION

The invention is directed to that type of container which is of a depththat the bottom is out of reach of a normal-sized packer. The containeris so formed and arranged that the packer has ready access to the innerbottom for the initial loading thereof. Such access is provided byproviding a reclosable opening in one of the main panels of thecontainer.

THE DRAWINGS

FIG. 1 is an isometric view of a container constructed in accordancewith the teachings of the present invention, the container being shownin a position with the closure flaps thereof in closed position;

FIG. 2 is a plan view of a cut and scored blank for forming thecontainer of FIG. 1; and

FIG. 3 is a view somewhat similar to FIG. 1, but showing the steps inclosing the container after the loading thereof by a packer.

The improved container according to the present invention is referred togenerally by the reference numeral 10, and is formed from a cut andscored blank 10A. Container 10 comprises opposed pairs of main panels11, 11, 12, 12A and 12B, these being connected seriatim along fold lines13. Panels 12A and 12B are glued in overlapping relationship alongportions 12C thereof, the remainder of panels 12A and 12B being ungluedfor reasons as will appear. The aforesaid panels 11, 11, 12, 12A and 12Bthus define a container tube. .[.Closure.]. .Iadd.Bottom closure.Iaddend.flaps 17 are foldably connected to the aforesaid main panelsalong a common fold line 18, and the flaps 17 are foldable into positionto define a bottom closure for the tube described.

.[.Second.]. .Iadd.Major top .Iaddend.closure flaps .Iadd.19.Iaddend.extend from opposite ends of the main panels 11 and 12 and arefoldably connected thereto along a common fold line 21.

.[.Closure.]. .Iadd.Minor top closure .Iaddend.flaps 19A extend frompanels 12A and 12B and are foldable with respect thereto along thecommon fold line 21.

A score line 20 is formed in each main panel 12A and 12B and extendsfrom edge 22 thereof to a corner of such main panel at score line 13connecting same to main panel 11. The score lines 20 thereby define apair of triangular shaped subpanels 23, 23.

The triangular shaped .[.panels.]. .Iadd.subpanels .Iaddend.23, 23,together with their connected minor .Iadd.top .Iaddend.closure flaps19A, are foldable along the score lines 20 to provide ease of loading ofthe tube or container body from the open side thereof, as seenparticularly in FIG. 3. After the loading of the container 10, thetriangular shaped subpanels 23, 23 are folded back into the plane of.[.their main.]. panels 12A and 12B, and the loading of the containerbody is completed. Thereafter, the minor .Iadd.top .Iaddend.closureflaps .[.22 and 23.]. .Iadd.19A .Iaddend.are folded into side-by-sideposition, seen in FIG. 1, and the remaining .Iadd.major top.Iaddend.closure flaps 19 are folded into overlapping and securedrelationship as by a suitable adhesive.
